Method Summary

Modifier and Type	Method	Description
`TimeIterator<V>`	`readBackward(Interval interval, ExecutorContext context)`	Read the given interval returning a reverse time iterator from the end to start.
`TimeIterator<V>`	`readForward(Interval interval, ExecutorContext context)`	Read the given interval returning a forward time iterator from start to end.
`void`	`write(Sample<V> sample, ExecutorContext context)`	Write a sample into the variable.

- Method Detail
  - readForward
```
TimeIterator<V> readForward(Interval interval,
                            ExecutorContext context)
```
    Read the given interval returning a forward time iterator from start to end. More specifically, return an iterator for all the samples whose interval overlaps or is contained by interval.
    
    Parameters:
    
    interval - The interval to read
    
    context - Evaluation context
    
    Returns:
    
    A TimeIterator reading the map forward for the given interval.
  - readBackward
```
TimeIterator<V> readBackward(Interval interval,
                             ExecutorContext context)
```
    Read the given interval returning a reverse time iterator from the end to start. More specifically, return an iterator for all the samples whose interval overlaps or is contained by interval in reverse order.
    
    Parameters:
    
    interval - The interval to read
    
    context - Evaluation context
    
    Returns:
    
    A TimeIterator reading the map backward for the given interval.
  - write
```
void write(Sample<V> sample,
           ExecutorContext context)
```
    Write a sample into the variable.
    
    Parameters:
    
    sample - The sample to store
    
    context - Executor context
